3.Повторите материал по возвратным местоимениям
We use reflexive pronouns: с with verbs such as behave, burn, cut, enjoy, hurt,introduce, kill, look at, teach, etc, or with prepositions when the subject and the object of the verb are the same
person. He (subject) introduced himself (object) to everyone in the room.с in the following expressions: enjoy yourself (have a goodtime), behave yourself (be good), help yourself (you arewelcome to take something if you want).Help yourself to some cookies; I’ve made a fresh batch.We use emphatic pronouns:с with the preposition by when we mean alone/withoutcompany or without help (on one’s own).He lifted the heavy couch by himself/on his own.I – myself, you – yourself, he – himself, she – herself, it –itself, we – ourselves, you – yourselves, they – themselvesс to emphasise the subject or the object of a sentence.Cindy drew this picture herself. (Cindy drew the picture. Noone else drew it.)
Bob was congratulated by the president himself. (Thepresident congratulated Bob, not someone else.)
Notes: сWe do not normally use reflexive pronouns withthe verbs concentrate, feel, meet, and relax. If youdon’t feel well, go home. (NOT: If you don’t feel yourselfwell go home.)с Reflexive pronouns are used with the verbs dress,wash, and shave when we want to show thatsomeone did something with a lot of effort.Despite having a broken arm, Ron managed to dresshimself.
